oneboxing: change to use [[[triple square brackets]]]

Browse source 
This is because for some reason when extending Parsedown to add a new 
block type for [[internal links]] to detect oneboxing means that it's 
impossible to  tell if we're inside e.g. a bulleted list or not :-/

@ -8,7 +8,7 @@ This file holds the changelog for Pepperminty Wiki. This is the master list of t
- Added support for embedding external YouTube and Vimeo videos (e.g. `![alt text](https://youtube.com/watch?v=pID0xQ2qnrQ)`)
- If you know of a cool service that should be supported, please open an issue - YouTube and Vimeo were just the only 2 I could think of
- Known issue: specifying the size (i.e. with ` | 500x400` inside the brackets `()` there) doesn't currently work because iframes are weird
- Added [oneboxing](https://meta.discourse.org/t/rich-link-previews-with-onebox/98088): rich previews for internal links. If an internal link is on it's own with nothing before or after it on a line, then it'll be turned into a onebox
- Added [oneboxing](https://meta.discourse.org/t/rich-link-previews-with-onebox/98088): rich previews for internal links. If an internal link with 3 square brackets (e.g. `[[[example]]]`) is on it's own with nothing before or after it on a line, then it'll be turned into a onebox
- 2 new settings have also been added to control it: `parser_onebox_enabled` and `parser_onebox_preview_length`
- TODO: Update the dynamic help page for this.
